| 中文摘要: |
| 分析实心轮胎生产过程中常见的质量问题，并提出相应的解决方法。常见的质量问题主要包括轮胎表面气泡、胎侧重皮、橡胶与金属粘合不良、表面撕裂和胶须断裂、变色、花纹块窝气、冠部裂口、冠部露中间层等，通过调整操作工艺规程，使操作标准化、制度化、稳定化，及对出现问题较多的规格产品制定专用生产工艺，重新确定硫化条件，调整和优化胶料配方硫化速率匹配性等措施，成品轮胎一次合格率由99.1%提高到99.8%，退赔率由0.2%减小到0.05%。 |
| 英文摘要: |
| The common quality problems in the production of solid tire were analyzed，and the corresponding solutions were put forward.The common quality problems mainly included air bubbles on tire surface，skin lamination on sidewall，poor adhesion between rubber and metal，surface tear and fracture of vulcanized rubber hair，discoloration，air under pattern block，crown crack，and exposed intermediate rubber on crown，etc.By taking the measures of adjusting operation process procedures，making the operation standardized，systematized and stabilized，and for the products with more problems，developping special production process，redetermining the vulcanization conditions，adjusting and optimizing the matching of curing rate of rubber formulas，the first pass rate of finished products was increased from 99.1% to 99.8%，and the return rate was reduced from 0.2% to 0.05%. |
